Hi Sagar,
The passage states that films are fundamentally visual tools of expression while "words tend to be the tools of playwrights". This is inclining towards a concept of utility, indicating that films are distinct from plays. However, the use of the word "nevertheless" presents this juxtaposition as being indefinite. The author is saying that, despite this difference in expression, many films have been derived from plays indicating that their tool of expression might be less visual and more dialogistic.
Our task here is to find a statement opposing this idea of overlap presented above.
Statement A is irrelevant since no such discussion is undertaken.
Statement B is inaccurate since no discussion with regard to the style of films is made.
Statement D is untrue since no such implication with regard to the quality of the film is made.
Statement E is rejected as well since the aspect of the literary critic is nowhere close to the idea that is presented above.
Statement C is the closest to the idea discussed in the passage. Since the passage is stating that films are not limited to visual expressions, Statement C is rejecting this idea. Hence, it opposes the main point presented in the passage. I hope this clears your doubt!
